My friend bought a 820 from a good Canadian retailer Gibbys.

I went to his house to set it up. Good thing I brought my SPL meter.

Onkyo dropped Audyssey for This????

I have used Pioneer, Yamaha and even Harman's old crappy setup.

Never have I come across a more crappier auto calibration system.

One position. One. In 2019 in a upper level receiver!

It set the crossovers to 200hz for the towers. Wtf..... why even bother including this stupid thing....

The only thing it got right was the distance of the speakers.

Great receiver... horrible calibration system.

That's why after owning my TX-NR676 for about a year, I'm already upgrading to a Denon (arrives Thursday). Had Onkyo for years, even back when they used Audyssey. Since then, I've owned a 656 and now this 676, both with AccuEQ, and hate it. Don't get me started with the lip sync issues. Can't wait for my Denon.

What sucks is I've been an Integra user for years.

I currently have the 60.5 pre pro.

It has XT32.

I don't ever see myself buying another Integra since they use their own garbage system.

Wow! I am still floored by how inaccurate that setup was.

Hope you have a temp controlled room cause you can use D/M AVRs as hot plates. My 820 never gets beyond warm even after 4 hours of loud movie watching. And at ambient room temps in the mid 70s to lower 80s depending on time of year.

Maybe the EQ microphone is defective..

Just my $0.02...

You really don't think that other ARC systems don't ever come up with incorrect crossovers?

I ran mine a total of 4 times, twice it was correct, twice it also came up with the odd 200hz. Move the mic an inch or two and it can affect the results. Nothing wrong with one mic position as it's impossible to calibrate for a wide space without making compromises within that space.

I sit in one position, why would I need to have a mic in 10 other positions?

The room and speakers are much more important than someone else's idea of what your speakers should sound like.

After upgrading from a 2009 HK it was like I got new speakers and the bass was much better. The extra power is most likely the reason for the better speaker performance because I really can't tell any difference with AccuEQ on or off. I just leave it on anyway. All it took was a little manual tweaking to get the bass setup.

The subEQ of Audyssey is about the only part of that ARC that might be useful to more people depending on the room setup. There are many users that much prefer how their setup sounds with AccuEQ than with Audyssey, especially the bass.

Bottom line, move the mic a little, use a mic stand or at least a tripod and run it again or just don't use it and do a manual setup it's not that hard.

That's what I'm concerned about. It's an open entertainment stand. And I'm usually warm, so it rarely gets above 73 degrees in our house. I think I'll have room for some fans on top if needed.

I've used Sony ES receivers since I was a kid(I'm 46) but just this past week, I moved to an Onkyo TX-RZ630 because I wanted to upgrade from 5.2.2 to 5.2.4 and Onkyo has the most sensible price for a 9 channel receiver. Back on subject, Sony has their own proprietary software for setting up your home theater and they even use a stereo mic. After using my new receiver, Onkyo's software is light years ahead of Sony's! I mean my Sony would play like 5 Notes as call it a day "yup, she's ready to go" and it doesn't even take 20 seconds! So trust me, there's a lot worse out there than Onkyo's AccuEQ. I just got my new SVS Prime center and a new A/V rack today, so I'm having a blast re-wiring it right now. I'll definitely use AccuEQ to get my base, not like you can't tweak every parameter manually.

I prefer AccuEq over Audyssey. Different rooms and different ears. It does require some adjustments post calibration, but it doesn't jack with the midbass like Audyssey does.

I've used YPAO, Audyssey XT, Audyssey XT32 and now basic MCACC on a new Pioneer SC-LX502 that i bought this week and to be honest i like what basic MCACC did in my living room set up over all of them!

Like some already said here, you must get a good mic stand and play with mic location to get good results. I had to fiddle with Audyssey XT32 many many times to get the results i wanted. I only had to run MCACC 4 different times. Room prep, speaker placement and good mic stand is a must for good results!

Maybe the ears at Onkyo/Integra are defective.

Have you done the accueq advanced setup yet with the rz630? How do you like it?

you should of known to run it several times.
ive tried both, and my onkyo sounds way better than the denon 3500 i took back a few months ago.
they overbaked xt 32 bad if you ask me.
sounded fake.

My Onkyo NR-676 sounded off no matter what I did, some type of treble issue with my speakers.
Maybe it was just my speakers, though I seemed to notice it a little even with my rear surrounds on the Onkyo.
AccuEQ didn't seem to help the issue at all.

I am getting a Denon again (supposed to arrive today --- yeehoo), still have the Onkyo as well.

I never even felt a need to adjust a Denon, seems fine OOTB after doing a basic level adjustment. I just set the levels by ear with the tone and I was done.
With the Onkyo, I tried for a year multiple settings, never did sound right. I even tried using EQ software through an HTPC, bah no help.
The high frequency resonation issue on the Onkyo was too extreme, unfixable. Maybe some people just cannot hear it like I can, who knows.

YMMV, but IMO Denon is ahead of the Onkyo sound-wise, but again maybe some speakers go the other way.

I was never a big Denon fan, I think their quality is not what it was in the 80's. I have run the advanced AccuEQ on my TX-RZ630 and it gets the measurements perfectly, it does tend to leave it tonally flat and pulled way back on individual volumes. I set my own crossover points and other than rolling the treble up a hair, the AccuEQ works pretty good in my opinion. I got everything back together at like 2am this morning.

Just got the Denon x3400h partially hooked up, I think it is just how certain speakers match up to certain receivers for the most part.
Denon is definitely warmer, whereas the Onkyo has more treble and is whispier.

I did notice the Onkyo sounded very good with my headphones, but not with my speakers (very weird).

The Denon sounds perfect with my speakers (Infinity), like the sound I always dreamed of, but the Denon sounds not any better (maybe slightly worse) on the headphones.

So odd, but I'll have to test more.

As long as you give the Denon enough space, you will be fine. If you are putting it on an open entertainment stand, you shouldn't need external fans.

Audyssey works for some people, not others. I'm super lazy, but all I have to do to fine tune an Audyssey calibration in my room is to turn up the subwoofers 3 db, and I'm flattish to 10 Hz.
I have it limited to 500 Hz now, just because, but when I ran it full range a few years ago, it sounded good too, but I never measured it then.

That being said, I'm waiting to see how this new Dirac bass management works out, and if it will be available on a minidsp.

I wouldn't dare run any Denon without active cooling, unless the room is 50 degrees.
The newer Onkyos actually run way cooler than the Denons.

Though the higher-end Denons may run cooler than the lower-end ones, I haven't pushed my new Denon hard enough to know yet.
I burned up 2 Denons from overheating, the Onkyo never even got hot.

The older Onkyos used to run like oven hot, but they fixed it and now they are some of the coolest receivers out there, especially for the ones that use A/B amps (like the 676,686).

I loved everything about the Onkyo more than the Denon, EXCEPT the sound of the Onkyo with my speakers.
For me, the sound is what matters, so back to Denon.

The protection/shut off circuitry in some Denons is a joke (doesn't work), or at least failed in my setup (twice!).
It should have shut itself off, but neither Denon did before burning up, and when I felt the receiver's case, they were very very hot.

Cmon man!.....what kind of thread title is this!?....jeeeeezzzz......moderators.........its like sayin’ ‘ what kind of POS r u’?.

I am no ‘Onkyo+man’.......but this is ridiculous.......I have done Lexicon mc12 calibration that hasn’t been up to snuff.

Tape measure and spl meter.....NEVER FAILS...........old school....

Have a great calibration everyone.....

I've recently switched from the the Yamaha 2060 to a Onkyo rz730 and I would say AccuEQ advanced is an upgrade, especially in the low end. It has 3 positions of measurement (the last two are for standing wave in my understanding). I may not be a fan of the graphic manual EQ but it's usable. AccuEQ advanced also set the crossovers a bit low, but again easily adjustable.

I understand the OP used an older version of AccuEQ and it may have been hot garbage (I've never heard it) but I'm pretty impressed with AccuEQ advanced. I'm not about to lump it with ARC or Dirac, but I would put it up against audyessy as competitive.

I went with the Onkyo tx-rz730 for one reason as I'm usually a Yamaha guy, it was an inexpensive route to 11.1(2) pre-outs. Not disappointed at all for the price.

I get a little chuckle when people talk about Denon running hot. I mean I had an Onkyo 805 and fans were a must. That said I think I'll be getting an X3500 to replace my 818. Audessy just works in my room.

I got the entry level Onkyo TX-SR393 recently and after using the setup mic, I got 50hz for my mission lx-2 fronts, 120hz for lx-c and 50hz for my denon sc-m39 rears. My previous yamaha htr3064/rx v371 used to give me 90 or 100hz for my mission lx-c centre speaker. So what I do is change crossovers for the fronts and rears to 80hz. As I've read before that its only ok to increase crossover frequency setting, so I left centres at 120hz. I mean its seems to sound ok so is it an onkyo thing or is the mic broken?

It depends on the correction system. At higher frequencies moving the microphone slightly can give a totally different result. Plus, your HEAD is not in EXACTLY the same place every time (unless you're sticking it in one of those things they use at the eye doctor ha ha). Audyssey is a time-based system, they state they are sampling the room as part of their algorithm.

Meanwhile all correction systems are dumb programmed machines with no common sense. So they can all be caught out and give weird results sometimes, especially if there are some odd acoustic conditions or cancellation going on.

I have the RZ920. I posted about AccuEQ in other threads how I thought it was better than Audyssey in my Denon x3100.

X3100 always set my LCR to large when it knew I had a sub on my system. Towers go down to 38 hz, center at 50 hz.

AccuEQ put put my LR as small, with a 40 hz crossover. I cannot recall offhand how it set my C.

So what's worse:
1. Denon Audyssey not offloading any LCR to my sub
2. Onkyo AccuEQ offloading LCR 40 hz and below to the sub.

I vote #1 is worse.

Either way, it's a simple flip if a few settings post-calibration.

As for multiple calibration points, the points are spaced too close together to be meaningful IMO. I think it's a marketing thing. I used with my Denon x3100... I have no idea if it was better than a single point. I could not A/B the results.

It comes down to:
A. Give me one kick-ass calibration for the primary listening position
B. Provide lass than kick-ass calibration across 2 or 3 seats... they'll never know what they're missing 🙂
